2in Block & U-Bolt Kit

The ROUGH COUNTRY 2in Block & U-Bolt Kit (SKU RCS6557) is a complete leaf spring lift solution engineered for full-size Ford trucks from 2005–2010, delivering a straightforward 2-inch chassis lift for improved ground clearance and suspension geometry. As a mechanic, you'll appreciate that block-and-bolt systems remain the most reliable method for controlled lift—they work by compressing the leaf spring stack or adding preload, raising the frame without replacing springs entirely. This kit is ideal for owners seeking budget-conscious suspension upgrades before tackling bigger jobs, or as a foundational lift for trucks already running heavy loads or aggressive tires.

Built from solid steel and finished in black powder coat, the 2in Block & U-Bolt Kit resists rust and corrosion in harsh road conditions while maintaining structural integrity under dynamic suspension articulation. The U-bolt design clamps the block and spring securely to the axle housing, ensuring zero slippage during acceleration, braking, or off-road impacts. At 19 lbs and compact dimensions (5.75 x 6 x 25.5 inches), the kit is easy to handle during installation—a critical factor when you're working in a shop bay or driveway. The included hardware eliminates the need to source separate fasteners, reducing assembly time and ensuring OEM-grade fit.

Ford truck owners upgrading to larger tires or needing additional ride height will find this rear-mounted lift kit particularly effective—it pairs well with front leveling kits or coil-over conversions as part of a staged build. Installation is straightforward: remove the axle U-bolts, insert the blocks between the spring and axle, and torque new U-bolts to spec. Compatibility is confirmed for 2005–2010 Ford full-size trucks (F-150, F-250, F-350), making this ROUGH COUNTRY solution a trusted choice for thousands of builds across North America.
